De Buyer Mineral B Crepe Pan causes smoke alarm to go off

I am having several issues with my new De Buyer CS Mineral B Crepe pan. The most urgent one is that the two times I've used it, it sets the smoke alarm off. I use it on medium or under medium heat on my electric ceramic cooktop, and I use canola oil. I have cooked South Indian dosas on it, nothing else so far. Not sure what I'm doing wrong, or do most of you who use these pans put your vent fan on while you are cooking? Thanks all!

I guess it is a ductless, recirculating vent that blows back into the kitchen. If it had a duct and exhausted outside, it shouldn't blow anything back inside...that's why I asked about the dust. If a true exhaust fan is blowing back in, then there could be deeper issues.

Update: my pan is working perfectly, almost completely non stick and seasoned. Dosa's are looking and tasting great too, I just have to work a bit on my spreading in concentric circles technique! I've learned to use less oil and cook on a lower flame, so no smoke alarm going off!
